Geosteering
Geosteering, also called real-time well placement, is a drilling technique that uses real-time geological data to keep the wellbore within the target reservoir, mainly in horizontal wells.
Geothermal district heating
Geothermal district heating supplies heat from underground hot water reservoirs through a shared pipe network to many buildings; global capacity reached about 13 GWth in 2019, delivering roughly 163 PJ per year.
Geothermal doublet
A geothermal doublet is a pair of wells drilled into the same geothermal reservoir: a production well brings hot water up, and an injection well returns the cooled water.
Geothermal energy
Geothermal energy is heat drawn from reservoirs of hot water and rock beneath Earth's surface, used directly for heating or converted into continuous, carbon-free electricity.
Geothermal play fairway analysis
Geothermal play fairway analysis (PFA) is a statistical exploration method, adapted from oil and gas, that combines geologic datasets into favorability maps for finding geothermal resources.

Geothermal reservoir engineering
Geothermal reservoir engineering is the branch of reservoir engineering that applies scientific principles to developing and producing geothermal reservoirs, predicting changes in pressure, temperature, and fluid flow.
Geothermal resource assessment
Geothermal resource assessment is the set of methods used to estimate the power or heat a geothermal field can sustainably deliver, relying mainly on the USGS volumetric method before drilling and numerical reservoir simulation during production.
